I really didn't know who was responsible for the pizzas at the Mayor's Election Night party, but I sent a message (I don't remember to whom/who to), but I got this response when I sent photos and thanks to several people including the person who responded:

Also Tina -- I want to apologize to you! Your feedback on the lack of vegan pizza at the Mayor's election night party was shared with me. As the person responsible for said pizza and as a vegetarian myself, I acknowledge that I made sure to have veg options but not vegan (or gluten free). Sorry! Will continue to try to do better for future events. Appreciate you so much.

So now I know, and I appreciate that--and her--so much!
